### Balance the following chemical equations KFFeO 13 Cal + 16- NassoS 17-.docx

1. Balance the following chemical equations KFFeO 13 Cal + 16- NassoS 17- Find the A) MgSOe Mg- S- PD= Fe- o- Solution 10. 3O2(g) ---------> 2O3(g) 11. 2KF + FeO -------> FeF2 + K2O 12. P4 + 6H2 ---------> 4PH3 13.C4H8 + 6O2 ---------> 4Co2 + 4H2O 14.2KClO3 ------------> 2KCl + 3O2 15. Ca(OH)2 + H2So4 --------> CaSo4 + 2H2O 16. Na2SO3 + S ----------> Na2S2O3 17. A. MgSo4 --------> Mg^2+ + SO4^2- SO4^2- x + (-2*4) = -2 x -8 = -2 x = 6 s = +6 Mg = +2 S = +6 O = -2 B. Pb3(PO4)4 ---------> Pb^4+ + PO4^3- PO4^3- x + (-2*4) = -3 x-8 = -3 x = +5
2. P = +5 Pb = +4 P = +5 O = -2 C. Fe2(CO3)3 -----------> Fe^3+ + CO3^2- CO3^2- x + (-2*3) = -2 x -6 = -2 x = +4 C = +4 Fe = +3 C = +4 O = -2
